Ultraviolet pulsed xenon bulbs are designed to pulse high amounts of UV light. These pulses last a few milliseconds with peaks in the UV-A, UV-B, and UV-C parts of the ultraviolet spectrum. These lamps are used in specialized UV equipment for disinfection.
How Pulsed UV Works
Pulsed UV light sources emit extreme amounts of full spectrum ultraviolet light, resulting in high levels of disinfection. They are available in wattages high above mercury lamps.
When the pulsed UV lamp is powered, it emits a broad spectrum of UV light (100-1,000nm), with peaks in the UV-A, UV-B, and UV-C ranges.
Is Pulsed UV Xenon More Effective Than UV-C Mercury Lamps?
While some sources have suggested that pulsed light disinfection is more efficient than using mercury ultraviolet bulbs, most studies comparing the two have shown no significant advantage to pulsed xenon lamps.
Under certain conditions, pulsed UV may offer an advantage due to its greater ability to penetrate through certain materials like liquids or foodstuffs.
